Review: Noticeable results without side effects - I’ve been taking this magnesium L threonate for a while and it’s been solid. The capsules are easy to swallow and don’t cause any stomach issues, which I’ve had with other types of magnesium. What I’ve noticed most is better sleep and feeling more clear headed during the day. It’s not some overnight miracle but it’s consistent and that’s what matters. Clean ingredients and no laxative effect makes it worth sticking with.

## Questions & Answers

**Q: Other ingredients detailed list please. why there is no pic of other ingrdts.? fillers? rice?**
A: Hey there! You're right there is no pic, but if you scroll down to important information you will see the full ingredient list. They are: Magnesium L Threonate (Magtein), Hypromellose (capsule), Rice Flour

Thank you.

**Q: Still not satisfied with answer - does formulated in usa mean actually sourced and packaged in the usa, stop wordsmithing, be directly honest here!**
A: It means made in the USA. It doesn't always mean formulated and/or packed in the USA. Most companies now will actually state, Made, formulated and packaged in the US If they are truly a U.S. company.

**Q: To the seller: source from china please? (not manufactured or made). but is the source china please?**
A: This formula is purchased from AIDP which is the company that holds the patent for Magnesium Threonate (Magtein) Thank you.

**Q: Why is magnesium in the threonate form at such a much higher milligram dose than all others? like over 4x higher.**
A: Magnesium assists in over 300 processes in the body, mostly neurological.  There are various forms of magnesium depending upon how it is processed (i.e. magnesium oxide: magnesium lysine glycerinate chelate, etc.)  I take this form at 2000 mg after reading research regarding its effect on brain functions.  You will need to do your own research regarding why you are taking magnesium.  Magnesium as a supplement is important.
